Summary

The purpose of this project was to establish a collection of datasets that could be used (1) to analyze the influence of partnership networks on the transmission of sexually transmitted and blood-borne infections, and (2) to examine the influence of study design on estimation of network properties and impacts. Eight studies contributed datasets to the collection.

Each study contains information on sexual, needle sharing, and/or social networks. Each dataset was harmonized to permit comparative analysis. Almost all of the studies were research projects funded by federal agency sources (e.g., United States Centers for Disease Control and the National Institutes of Health); one was funded by Canadian sources. These studies, all closed for further enrollment, provide a range of designs and study types as well as a range of transmitted diseases. This allows researchers to investigate the relative effect of personal behavior and network connections on the dynamics of disease transmission, and to explore the impact of sampling design on estimation of network properties. Respondents were asked questions about different test results such as HIV, chlamydia, syphilis and hepatitis. Demographic variables include race, ethnicity, marital status, age, and gender.

N = 95 respondents, interviewed up to 5 times each at 6-month intervals

Age = 18 and older

Sampling strategy: Random walk for
six seeds chosen at random within the same geographic area (Flagstaff) from persons presumed
to be at elevated risk for HIV acquisition (through sex and/or drug behaviors).

N = 228 respondents, interviewed up to 5 times each at 6-month intervals

Age = 19 and older

Sampling strategy: Random walk for six seeds chosen to originate from three distinct regions (two individuals chosen from each of three regions) -- from persons presumed to be at elevated risk for HIV acquisition (through sex and/or drug behaviors).

2011-08-09 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
